Supporting device special for injection mold machinery

The utility model relates to the technical field of injection molds, in particular to a special supporting device for injection mold machinery, which comprises a base, a placing block, a driving component and a connecting rod, the connecting rod is positioned above the placing block, a fixing plate is arranged at the bottom of the connecting rod, and sliding rods are arranged on two sides of the connecting rod. The fixing plate is connected with the two sliding rods in a sliding mode, the buffering component comprises two damping springs, dampers are arranged in the two damping springs, and the two ends of each damping spring are fixedly connected with the bottom of the fixing plate and the top of the containing block respectively. Specifically, when the upper mold and the lower mold are closed, the connecting rod is stressed to move downwards, so that the fixing plate slides downwards on the sliding rod, the acting force is eliminated by the damping spring and the damper, collision between the upper mold and
